I have a 18'x48" intex pool and the intex saltwater system. My daughter and I have been getting green hair. I researched on here and unplugged the copper part of the saltwater system and drained part of the pool. Still getting green hair so I did what the saltwater system book recommends under the troubleshooting section. It said to add aluminum sulfate. I researched that and it said to add the AS and let it sit overnight and then vacuum the next morning. I went out to vacuum this morning and there is a "cloud" all in the middle section of the pool. The rest of the water is clear. This isn't something I can vacuum up because it looks just like a cloud. If the "cloud" gets disturbed or I turn the pump on the whole pool becomes cloudy. Clearly I have screwed up by adding the AS. Does anyone know anything I can do to get my clear water back? I would rather deal with green hair than this! Thanks!
